Verdict
The clearest difference is in-app purchases: One Solution App at none against Mass Email's 13. One Solution App also leads on ads (none vs shown). Mass Email's advantage is update cadence (daily vs every 5 weeks) and ratings volume (7 vs 1). On price, rating and device support there is nothing between them.
